Looks good, fits good, works good
Style: Charging MagSafe Mount
I LOVE it! I bought the one with the cord at first and then returned it for the one without the cord and I'm 100% in love with it. It looks good, the magnetic strength is awesome and I love the fact that it can swivel around too

Very slow, but good quality
Color: 2White
It works as expected, but my phone says that it is a slow charger even when plugged in my fast charger brick. False advertising. Really wish it charged a little faster

Slow As a Turtle
Color: 2White
Super slow charging. After 10 minutes, my phone only charged 3%. I plugged my original charging cord into the same 65W charging block and after 2 minutes, it had charged nearly 10%.
